Solutions

Quick Diagnosis

This error typically shows up after an automatic head cleaning cycle or when starting the printer after a period of dormancy.

Step-by-Step Solution

  1. Power off the unit and unplug the power cable.
  2. Check for ink clogs or debris in the purge area under the printhead.
  3. Try a full power cycle.
  4. If the error remains, the pump mechanism is likely jammed with hardened ink.

Maintenance and Prevention

Print a test page weekly to keep the internal cleaning pump active, as inactive pumps are prone to drying out.

When to Call a Technician

The purge unit is a precise mechanical assembly; if the error doesn't clear, professional pump replacement is required.
